ap icatio messa es 14, ieee fseii l n'aissg sa f Be; it known that we, JOHN MITCHELL and of the King of Great Britain, residing in London, England, have, jointly invented C61t&11111l6W and 'useful Improvements Re lati'ngf to -Cuplings; for Railway and like cation; 1

In" the: copending' application; Serial N0.

578,730, a coupling'for railway andlilre V61 hicles' is descr bed in Wlnch'a separate member llltQIPOSQtl betweenf'the couplenhead and: thedr awbar permits relative deflection between-these parts in two planes mutually at right angles. This member is adapted to slide in a ferrule, surrounding; the drawbar,

' inserted :in' theheadstocl: or ina' box inem ber secured tothe" longitudinals or headstock, means being provided to prevent rela ferrule H surrounding; the reduced end 0' ative rotation betweenthe coupler head and the drawbar.

A main spring and a subsidiary spring support and centralizethecoupler head and take up the initial draft stresses; further draft and all buffing stresses are taken up by the mainspring; V V

The present invention consists in; a modification or improvement of the arrangement described in thisprior. specification I;

,According' to the invention, in order, to

means of a n'ut J threaded on the end of the facilitate the passage round curves, the memher acting as a universal joint iseiitended rearward's so that the vertical pin isbehind the headstock instead ofin front ofit as in the previouslv described constructions. The

vertical pinv is in front ofthe box member containing the draft and butting spring and the drawbar.- 7 l ,The box member 18 secured to thelongitudinals and may be placedat any required position between'the headstock and the cen tre of the longitudinals. V l f Between the buffer head and the ferrule inserted the front end of the'box member and acting as a guide for the drawbar there isprovided a hollow distance piece surrounding the extended portion offthd intermediate member between the' vertical and horizontal ping the latter of which is ar-' ranged as in the examples shown in said copending' application in frontof the head stocln' The distance piece is supported at the headstock and is free to move in 'ahorizontal plane about the'vertical' pin behind the headstock.
